Right. The Amiga is atypical. This PeeCeeoid is industry standard inside.

Of course. That's how I got as far as I did - I disassembled the box, located
a 34-pad spot on the motherboard where a floppy connector *should* go, then
used a VOM to trace the wiring between the internal 34-pin connector and the
external 25-pin connector. What stumped me was a lack of /MOTORON (pin 16).
All is now well. It boots Linux just fine. Thanks.
